Initial reports about Avengers: Infinity War suggested that Captain Marvel would be in the film, but it later became clear that she would be saved for Avengers 4. Directors Joe and Anthony Russo explained — and apologized for — the miscommunication.

Speaking to Entertainment Tonight, the Russos explained that the big reason that they might have misled people to believe that Captain Marvel was in Infinity War had to do with them collectively and repeatedly referring to the third and fourth movies in the Avengers series as one big 5+-hour movie.

ET: When [we] interviewed you on set last year, you said that Captain Marvel is in this and that you were — I’m going to quote you — “really, really proud of being able to introduce” her. Then we were told she’s not in the movie.

Joe: Yes. What we were doing was, I think, we were speaking about — because we were working on both movies at the same time — we were speaking about both films, as if they were one film in our minds.

The Russos still got to be the first set of directors to work with Brie Larson; while next year’s Captain Marvel — directed by Anna Boden and Ryan Fleck — will be released two months ahead of Avengers 4, the film is still in production and won’t be wrapped until later on this year.

As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment – the fate of Earth and existence itself has never been more uncertain.

The currently-untitled Avengers 4 features a cast made up of many of the key players in Infinity War — alongside newcomers like Brie Larson and Evangeline Lilly — and is scheduled to hit theaters on May 3, 2019.

5 Potential Marvel TV Shows To Rival HBO’s ‘Watchmen’

With Damon Lindelof, the co-creator of both Lost and The Leftovers, developing a Watchmen show for HBO, Marvel needs a new TV hit. Don’t get me wrong, I know Agents of Shield still has a huge following, but I stopped watching the Netflix shows during the second season of Daredevil. And FX’s Legion was just… okay for me. It’s not that I don’t love Luke Cage and Jessica Jones, but it’s not fair to put lower-tier characters like them in competition with a juggernaut like Watchmen.

HBO was clearly taking notes when Netflix started releasing their shows, so this seems like a great moment for Marvel to take some notes on their competition. If DC is going to churn out a Watchmen series, then Marvel needs to dig deep into their libraries to find stories worthy of being brought to the silver screen.

So hit Next to find out about five properties Marvel should consider adapting if they want to match HBO’s Watchmen.
